Answer 1

（1）13×（3.69-1.8）+1.11×0.13
=0.13×(369-180+1.11)
=0.13×190.11
=24.7143;
（2）4.27-3.35+5.73-2.65
=(4.27+5.73)-(3.35+2.65)
=10-6
=4;
（3） 46×25%+55×0.25-0.25
=0.25×(46+55-1)
=0.25×100
=25;
（4）7.01-2.625-3.375
=7.01-(2.625+3.375)
=7.01-6
=1.01;
（5）0.75×67.5+31×0.75+1.5×75%
=0.75×(67.5+31+1.5)
=0.75×100
=75;
（6）20分之3×108-0.15×8
=0.15×(108-8)
=0.15×100
=15;
（7）12.5×0.25×32
=12.5×8×0.25×4
=100×1
=100;
（8）808×125
=(800+8)×125
=100000+1000
=101000;
（9）3.8×8.4+8.4×5.2+8.4
=8.4×(3.8+5.2+1)
=8.4×10
=84
